1. A computer lock comprising:
at least one lock body, one guide seat, one lock tongue seat, one spring, one hook cylinder and one cable rope set wherein:
the lock body comprises a lock core, a lock casing and a lock control set; a lock control chamber is disposed inside the lock core to contain the lock control set and the lock core fits with an inner chamber disposed inside the lock casing, and the front side of the lock core is further formed with a shifting rod;
the guide seat is formed with an inserting groove at one side to allow insertion of the shifting rod of the lock core; the other side of the guide seat is formed with a convex cylinder disposed at the center thereof, and two first curved slants are disposed respectively at each of the two sides of the convex cylinder;
the lock tongue seat has a lock tongue outstretching from a first side and a seat body at a second side thereof, wherein the seat body has a hollow chamber with a concave hole disposed at the center thereof to allow insertion of the convex cylinder of the guide seat; and two corresponding second curved slants are arranged at the peripheral edge of the hollow chamber to be slidably engaged by the curved slants of the guide seat, the lock tongue seat being thereby displaceable in an axial direction responsive to angular displacement of the guide seat thereabout;
the spring fits with the lock tongue of the lock tongue seat;
the hook cylinder includes a main body having a front cylinder at a first side and a receiving space at a second side thereof, wherein a hook part is outstretching from an edge of the front cylinder's outer surface, and a through hole penetrates the bottom of the receiving space to allow insertion of the lock tongue, the front cylinder maintaining slotted engagement with the lock tongue to guide linear displacement of the lock tongue in the axial direction therealong; the receiving space contains the spring, the lock tongue seat and the guide seat; and
the cable rope set includes a ring seat connected to a rope body, wherein the ring seat has a penetrating hole to allow the ring seat to fit with the peripheral edge of the main body of the hook cylinder.

1. Field of the Invention
The present invention relates to a computer lock, and more particularly to a computer lock that is capable of being easily locked and operated in order to prevent the computer from being stolen.
2. Brief Description of the Related Art
The laptop computer has became more and more common; at public places such as library, coffee shop, office, or meeting room the laptop computer are used very frequently. This electronic device is not only expensive, but also stores valuable data inside; once it is stolen, it will cause serious inconvenience and great loss. In public, the laptop computer is under the risk of being stolen even when the user is only away from the table for a few minutes. Therefore, there are computer lock products entering the market to prevent stealing. The computer locks are mostly patented, such as prior arts of U.S. Pat. No. 5,493.878 and U.S. Pat. No. 7,100,403 (hereinafter the prior art.)
The lock actuation of the prior art is mainly of a crossmember 11 of a lock body's front end inserting into a rectangular slot 12 disposed on a computer 10's casing, as illustrated in
In order to overcome the deficiencies of the prior art, a primary object of the present invention is to provide a computer lock that is capable of being easily locked and operated in order to prevent the computer from being stolen.
With the above object in mind, the present invention provides a computer lock comprising a lock body, a guide seat, a lock tongue seat, a spring, a hook cylinder, and a cable rope set. The hook cylinder has a hook part extending outwards from the front end thereof The hook part is arranged at inner wall of a slot of a computer; by lock actuation of a key, the guide seat is actuated to guide the lock tongue of the lock tongue seat to outstretch forward and enter the slot along the guide groove on the front end of the hook cylinder. By the foregoing mechanism, the computer lock is of being easy operation and can be locked and unlocked conveniently to prevent the computer from being stolen.
The detail structure, the applied principle, the function and the effectiveness of the present invention can be more fully understood with reference to the following description and accompanying drawings, in which:
The above and further objects and novel features of the invention will more fully appear from the following detailed description when the same is read in connection with the accompanying drawing. It is to be expressly understood, however, that the drawing is for purpose of illustration only and is not intended as a definition of the limits of the invention.
With reference to
The lock body 2 comprises a lock core 21, a lock casing 22 and a lock control set 23. A lock control chamber 210 is disposed inside the lock core 21 to contain the lock control set 23. The lock core 21 fits with an inner chamber 220 disposed inside the lock casing 22, wherein a position-limiting ring B is used to limit the rotating position of the lock core 21, as shown in
Referring to
Please refer to
The spring 5 fits with the lock tongue 41 of the lock tongue seat 4 and the position-limiting actuates between the hook cylinder 6 and the lock tongue seat 4.
Referring to
The cable rope set 7 is a ring seat 71 connected to a rope body 72, wherein the ring seat 71 has a penetrating hole 711 to allow the ring seat 71 to fit with the peripheral edge of the main body 60 of the hook cylinder 6. The peripheral edge of the ring seat 71 is further disposed of an embedding seat 712, wherein the embedding seat 712 has an embedding hole 713 thereon to allow an embedding head 721 on one end of the rope body 72 to be embedded therein. The other end of the rope body 72 is fixed with a fastening piece 73 to form a loop 722, as illustrated in
The main body 60 of the hook cylinder 6 has an end surface 603, wherein a soft pad body 8 can be flatly disposed on the end surface 603 to reduce the contact friction between the computer lock A and surface 93 of computer casing 9, allowing a tighter attachment therebetween.
With reference to
To unlock the computer lock A, insert the key K into the keyhole 221 and reversely rotate the key K to turn the guide seat 3 to reverse 180 degrees, and thereby actuate the second support part 422 of the lock tongue seat 4 to move along the first curved slant 32 to the lowest section 321 thereof. The spring 5 is no longer being compressed and the spring force push the lock tongue seat 4 to move backwards to withdraw the lock tongue 41 from the slot 91. And then the front cylinder 61 of the hook cylinder 6 is detached from the slot 91.
While the invention has been described with reference to a preferred embodiment thereof, it is to be understood that modifications or variations may be easily made without departing from the spirit of this invention, which is defined in the appended claims.
